A network apparatus comprising a trunk end point associated with an Ethernet-tree (E-Tree) service in a network domain and configured to forward a frame that comprises a tag according to the tag in the frame, wherein the tag in the frame is a root tag that indicates a root source of the frame or a leaf tag that indicates a leaf source of the frame, and wherein the trunk end point is coupled to a second end point associated with the E-tree service outside the network domain.

Embodiments of the invention are directed to registering one or more endpoint devices to receive a notification and detecting a congestion event related to a storage area network. The storage area network includes the one or more endpoint devices. The notification is sent regarding the congestion event to the one or more endpoint devices that have been registered for the notification.

The present embodiments relate to providing near real-time communications from a public network to a private network. A first computing device in a public network can obtain data packets to be provided to the private network from an application executing on the first computing device. A trust module executed by the first computing device can authenticate the user, application, and the data packets to be provided to the private network and add metadata relating to the sending user, recipient user, etc. The data packets can be forwarded to the private network via a cross-domain system (CDS). The metadata and the digital signature on the data packets can be verified by a trust module executing on a second computing device in the private network. The second computing device can receive the data packets and store the data packets for subsequent actions to be performed in the private network.

A network device may receive one or more packets, and may determine a flow control parameter, a rate limiting parameter, and a statistical sampling parameter associated with a slow counter. The network device may determine whether the flow control parameter satisfies a first threshold, whether the rate limiting parameter satisfies a second threshold, and whether the statistical sampling parameter satisfies a third threshold. The network device may identify a counter event associated with one of the one or more packets, and may selectively assign the counter event to a fast counter when at least one of the first threshold, the second threshold, or the third threshold being satisfied, or to the slow counter when none of the first threshold, the second threshold, and the third threshold being satisfied.

Systems, methods, and computer-readable media are disclosed for a scalable process for validating multiple paths used for routing network traffic in a network using segment routing. In one aspect, a method includes identifying, by a first network hop, one or more second network hops, for each of the one or more second network hops, determining a corresponding flow label, the corresponding flow label including a corresponding test packet for validating packet forwarding between the first network hop and a corresponding second network hop, and performing a validation process for validating packet forwarding from the first network hop to the corresponding second network hop using at least the corresponding flow label. The method further includes determining a queue of additional network hops to be validated based on a result of the validation process, and iteratively validating packet forwarding for each additional network hop in the queue.

A network device inputs first network status information of the network device in a first time period to an ECN inference model, to obtain an inference result that is output by the ECN inference model based on the first network status information. Then, the network device sends an ECN parameter sample to an analysis device that manages the network device, where the ECN parameter sample includes the first network status information and a target ECN configuration parameter corresponding to the first network status information, and the target ECN configuration parameter is obtained based on the inference result. The network device receives an updated ECN inference model sent by the analysis device.

A bulk material tender includes a mobile frame, a hopper, and a discharge system. The mobile frame has a left side and a right side. The hopper is disposed on the mobile frame. The discharge system is configured to discharge particulate matter from the hopper. The discharge system includes a discharge auger, a deploying actuator, and a positioning actuator. The discharge auger presents a proximal end and a distal end. The deploying actuator is configured to selectively emplace the discharge auger in a stowed orientation and a deployed orientation, wherein the distal end is adjacent to the hopper in the stowed orientation. The positioning actuator configured to selectively emplace the discharge auger along the left side and the right side of the mobile frame. Once emplaced, the discharge auger discharges particulate material from the hopper toward a target location.

A system and method is provided for sending congestion notification messages through L3 networks. For example, a data packet is received at a first switch in a first fabric block of an L3 network, and the first switch performs source MAC tagging of the data packet. The data packet is then forwarded to a second switch in a second fabric block of the L3 network, and the source MAC tag is maintained by the second switch and any intermediate switches. The second switch determines, in response to receiving the data packet, whether it is congested, and generates a notification message if it is congested. The notification message is L2 forwarded to the first fabric block, and further forwarded from the first switch to a source of the data packet using ACL matching.
